Correct waist circumference measurement method

Measuring waist circumference is the easiest way to understand the risk of cardiovascular disease, and only one tape measure is needed.

The correct way to measure the waist circumference is to use an inelastic tape measure with a minimum scale of one millimeter when standing naturally with feet 30-40 cm apart, and put it at the end of the connecting line between the upper edge of the measured hip bone and the lower edge of the twelfth rib (usually the narrowest part of the waist).

Circle the abdomen horizontally. When measuring, the tape measure should be tightly attached to the skin, but the skin should not be strangled; Measure the length of waist circumference at the end of normal exhalation, accurate to millimeter. It's best to ask your family to help you measure to avoid visual errors.
